What was discovered

The disappearance of the ships Erebus and Terror in 1845 set off dozens of search expeditions that mapped much of the Canadian Arctic archipelago and clarified its navigable passages. Inuit testimony and the remains found by Rae and McClintock reconstructed the expedition's fate.

Robert McClure was the first to traverse the Northwest Passage (by ship and sled, 1850-54), but Franklin is often cited as its discoverer because of his death; the Erebus (2014) and Terror (2016) wrecks were found following Inuit accounts. The first complete crossing by ship was Amundsen's.
